AUDIO INPUT CONNECTIONS
Eight Channel AES/EBU Input
The JSD-60 accepts eight-channel AES/EBU audio, typically from the digital cinema server (DCS).
The JSD-60 includes a DB25F connector using the Dolby® DMA8 pin out and an RJ-45
connectors using the StudioHub
pin out. The first six channels are loudspeakers assigned by
industry convention. The remaining channels can be configured by the user (i.e., sources for
HI/VI-N, Lrs, Rrs, etc.). For convenience, all connector pin outs are listed in Appendix A.
Six Channel Analog Input
The JSD-60 six channel analog input is on a DB25F connector. The analog inputs are active
balanced (differential) inputs. They may be driven by balanced or unbalanced sources. When
driven by an unbalanced source, the negative input should be connected to the low side of the
source at the source equipment to minimize ground loop noise. The cable should be twisted
pair with individual shields, even when driven by an unbalanced source. The DB25F connector
uses the THX® pin out as specified in the table in Appendix A.
Two Channel Analog Input
The JSD-60 has a stereo analog input (Non/Sync) on two RCA connectors. Connect these to an
appropriate source using RCA cables. Various stereo decode methods are available in the
system. These allow direct driving of the left and right speakers, adding a synthesized center
channel, surround, and custom mix for all output channels.
Two Channel Digital Inputs
The JSD-60 has an S/PDIF input and a TOSLINK input.
•
S/PDIF Input.
A stereo digital input on an RCA connector marked COAX. It is a standard
S/PDIF (Sony Philips Digital Interface) input. Connect to appropriate sources with 75 ohm
coaxial cable with RCA connectors on each end. As with the other stereo inputs, various
decode methods are available.
•
TOSLINK Input.
A TOSLINK optical digital stereo input is included on the JSD-60. Connect
this input to an appropriate source with a standard TOSLINK cable. As with other stereo
inputs, various decode methods are available.
Single Channel Audio Inputs
The JSD-60 has a public address (PA) and real time analyzer (RTA) microphone input.
•
PA/RTA Microphone Input.
Plug a PA microphone in to the combination XLR / ¼” stereo
(TRS) phone jack. The microphone input may be configured to drive the main or the
surround speakers. In addition, the PA microphone input can drive the RTA for room
equalization.
The jack is a combination XLR and ¼” TRS (stereo) connector. The XLR input is
